Pure fluorine is a pale yellow, highly corrosive, poisonous gas. It allegedly has a very pungent odor, although since inhalation of the gas is extremely dangerous, this is difficult to verify. It is essentially impossible to find pure fluorine in nature, since the highly reactive element readily...

What is the valency of fluorine and how to find it? What is the difference between an isotope and an element? What element has 53 protons and 74 neutrons? What is the atomic number for bromine? What is the Bohr model for fluorine?
fluoride was used by the germans and the russians during World War II as a means of 'dumbing down' its prisoners, making them easier to handle, less likely to revolt. And we have been sold the same product, that has nothing to do with teeth. think on world!

furthermore, it is not only determined when an atom loses an electron. for example, fluorine has 7 electrons in its outermost orbital. it is hard to lose 7 electrons and so it completes its octet by gaining 1 electron. since it gains 1 electron, its valency is 1. in the periodic...
